Comment 4 for bug 1589690

We found the issue it had to do with baremetal install of ubuntu on POWER8 requiring SMT to be disabled

sudo ppc64_cpu --smt=off

Also change location back to --cdrom

virt-install --debug \
--name=guest100-ubuntu1604 \
--controller type=scsi,model=virtio-scsi \
--graphics none \
--console pty,target_type=serial \
--disk pool=virtimages,size=20 \
--vcpus=2 \
--ram=2048 \
--os-type=linux \
--os-variant ubuntu16.04 \
--network bridge=MarkIII_vlan91 \
--cdrom=/images/ubuntu-16.04-server-ppc64el.iso
